libstdc++.la and it's libdir

Hi,

I'm doing a personal project where I am building a new rootdisk for my DNS-323 (an ARM machine).

I use buildroot from 20080430 (currently) with gcc-4.2.3. Although I have a few patches to make things work, I don't have anything that touches gcc.

Now over to my problem:

The libdir variable in libstdc++.la (residing
in /path/to/buildroot/build_arm/staging_dir/usr/arm-linux-uclibc/lib/libstdc++.la file is wrong. It says:

libdir='/usr/arm-linux-uclibc/lib'

where I would have expected it to say:

libdir='?/path/to/buildroot/build_arm/staging_dir/usr/arm-linux-uclibc/lib'

This causes problems when using libtool. I.e, I compile a c++ libary (in this case libsigc++-2.0) and then that library gets in it's .la file a dependency for ?/usr/arm-linux-uclibc/lib/libstdc++.la and when I in turn compile a program that uses libsigc++ libtool fails because it can't find /usr/arm-linux-uclibc/lib/libstdc++.la.

If I manually edit libstdc++.la for it to point to the correct place, things work as expected when I recompile my dependent libraries.

Have anyone else had this problem and have any idea where I should look for a more permanent fix instead of doing things manually. I know I can probably use sed somewhere to change the offending line, but I would really like to know why it sets it wrong the first time around.

Any help is appreciated.
